COMBING-MAGHINE.

Application filed July 31, 1914. Serial No. 854,802.

To all whom it may concern:

Be it known that I, RUDoLr Gii'rERMA N, a subject of the Emperor ofGermany, residing at Perosa Argentina, Piemonte, Italy, have inventedcertain new and useful Improvements in Combing-Machines; and I do herebydeclare the following to be a full, clear, and exact description of theinvention.

This invention relates to a combing machine of the type comprising asingle or double combing segment adapted to be moved between the feedingand the stripping devices. 7

A primary object of the invention is to provide an improved combing.machine of the type described in which the combing segment, or eachcombing segment if more than one, is arranged to rotate about an aXisparallel with the feeding and stripping dc vices, one or other of thesaid devices being located within the circle described by the revolvingcombing segments.

This novel arrangement has the advan-' tage of enabling the combingsegments'to be made of a relatively large radius, so that the path ofthe individual combs when passing through the beard or projecting endsof the fibrous material is no longer an arc of very small radius, butone of large radius, whereby the work of the combing segments is greatlyfacilitated. In addition, this arrangement admits of the number of comb-bars on a segment-being materially in creased.

To this and other ends, the invention consists in the construction,arrangement and combination of parts described hereinafter and pointedout in the claims.

Two illustrative embodiments of the in: vention are represented by wayof example in the accompanying drawings, wherein:

Figure 1 isa vertical section showing the essential parts of atwo-headed combing machine having combs arranged on the in side of thesectors, and in which the combs rotate about. the feeding and cleaningdevices,and Fig. 2 is a like view of a twoheaded combing machine havingcombs arranged on the outside of the sectors; Fig.

and Fig. 17 is a top plan view thereof; and V Fig. 18 is a verticalsection through the entire combing machine; in this view the drivingwheels of the various parts are shown onlydiagrammatically. Figs. 19 and20 are respectively side elevation and plan of the mechanism foractuating feed rolls 38 and 38 and Fig. 21 is a view similar to Fig. 19but-showing the parts in different position.

Referring firstlyto Figs. 1, 3 and 18, the 8 machine frame 1 comprisestwo side walls which are connected together by rods 2 and carry variousshafts referred to hereinafter.

The-stationary hollow shaft 3 on which the hub or sleeve 4 rotates iscarried by this frame, and the arms 5 and 5 of the combing segments 6and 6 respectively, are carried by this hub. The combing segmentsaredisposed at right angles to their arms and carry pins 7 and 7,respectively, on their inner sides. Gear wheels 8 and 9 are keyed on thehub 4 at the two sides of the arms 5 and 5. The inner gear wheel 8 isadapted to drive the devices located within the revolving segments,namely the two feeding devices and the cleaning device, which arecarried on one side by the inner side wall 10 extending downward besidethe plane of rotation of the arms 5 and 5, and on the other side by theframe 1. The outer gear wheel 9 meshes with the gear wheel 11 of themain driving shaft 14 which is journaled in the frame 1 and carries thefast pulley 12 and the loose pulley 13. Consequently, when the pulley 12is driven the arms 5 and 5 and the combing segments 6 and 6 are rotated.The outer gear wheel 9, which is of larger diameter than the inner gearwheel 8, also drives the stripping devices by means of suitabletransmission gearing.

Referring now to Figs. 4, 5 and 18 showing the left-hand feeding device,the combing segments comb on the left-hand side of the machine fromabove downward. Accordingly, the lower aw 15 of the clamp of the feedingdevice is rigidly connected with a crosspiece 16 which extends from theframe 1 into the space between the segments and is connected on theother side with the Wall 10. The upper jaw 17 of the clamp is movableand is attached to one end of two symmetrical two-armed levers 18, thepivot pins 19 of which are each carried in an eye 20 of a bracket 21mounted on the crosspiece 16. The other end of each of the levers 18 ispivotally attached to a rod 22 which is connected by means of a pivotpin 23 with one arm of a two-armed lever 24 free to rotate about a shaft25 carried by the frame 1 and by the side wall 10. Each rod 22 issurrounded by a coil spring 26 which bears at one end against a collar27 on the rod 22 and at the other end against a collar 28 fast on theframe 1 or the wall 10. The other arm of each lever 24 carries ananti-friction roller 32 which co-acts with a cam 29 keyed on the shaft30 journaled in the frame 1 and in the side wall 10. A gear wheel 31which meshes with the gear wheel 8 is also I keyed on this shaft, sothat the clamp is actuated by the shaft 14 by means of the gear wheels11, 9, 8, 31, the cam 29, the two-armed levers 24, the rods 22 and thetwo-armed levers 18. The left-hand feed mechanism comprises a carryingframe 33 having two grooves 34 and 35 for suspending the pivots of apress roll and a feed or licker-in roller, and a recess 49 for a guideroller 50 The two side walls of the carrying frame are connected withone another by the guide plate 36 which has an aperture at 37 for thepassage of a lower feed roll 38. An aperture 37-" for an upper feed roll38 is provided at the lower end of the guide plate 36. The frame 33 issupported at either s1de by two links 39 and 40 mounted on the frame 1and wall 10. Each of the two front links 39 is pivotally connected atone end by means of the pin 41 with the lower part of the carrying frame33 and at the other end, by means of a pin 42 with an eye 43 mounted ona cross-bar 44 connecting the frame 1 with the wall 10. Each of the tworear links 40 constitutes an angle lever rotatable about a shaft 45mounted in the frame 1 and wall 10. The upper end of each angle lever 40is connected by the pivot pin 46 with the carrying frame 33 and thelower end thereof carries an antifriction roller 47 running on a, cam 48fast on the shaft 30.

The carrying frame 33 is moved to and fro by the driving shaft 14 bymeans of the gear wheels 11, 9, 8 and 31, like the clamp mechanism, andby the cam 48 and the an gle levers 40. A spring acting on the carryingframe 33 tends to move the same backward so that the roller 47 alwaysbears against the cam 48.

The feed rolls 38 and 38 journaled in the carrying frame 33, areintermittently rotated by pawl and ratchet mechanism. On the axle of theroll 38 is fixed a ratchet wheel 52, and loosely arranged on the sameaxle is a two-armed lever 50, the upper end of which is journaled on aboss 49 on an arm 49, fixed to the frame 1. On the arm 50 of this lever50 is journaled the pawl 51, engaging the ratchet wheel 52 of the feedroll 38. The lower end of the lever 50 is connected by a link 53 to alever 54, loosely arranged on the axle of the second feed roll 38. Thislever 54 is provided with a pawl engaging the ratchet wheel 55 fixed onthe feed roll 38. When the carrying frame 33 is moved from its forwardposition, shown in Fig. 19, to its rearward position shown in Fig. 21,the lever 50 swings to the right band (Fig. 21) on its pivot 49, thepawl 51 therefore is pushed down and rotates the ratchet wheel 52 andthe feed roll 38. Simultaneously the lever 54 is swung by the link 53 tothe right hand, and the pawl 55 rotates the feed roll 38. lVhen thecarrying frame 33 is moved again in its forward position the levers 50and 54 are swung to the left hand, and the pawls 51 and 55 are broughtin engagement with other teeth of the ratchet Wheels 52 and 55 The feedor pusher plate 56 which when the clamp is open brings the combed beardor length of fibrous material to the stripping device slides between theguide plate 36 and the lower jaw 15 or the crosspiece 16, to which thelatter is attached. This pusher plate is bent about the feed roller 38and is attached by means of a pivot pin 57 to one arm of an angle lever58 rotatable about the shaft 25, the other arm of said lever beingprovided at its end with an antifriction roller 59 which bears against acam 60 keyed on the shaft 30. A spring acting on the arm 58 tends tomove the plate in the opposite direction, so that the same driving 3means are used for reciprocating the plate as described above for movingthe jaw 17 and the frame 33.

The right-hand feeding device will now be described with reference toFigs. 6, 7 and 18. As the combing segments on the right-hand side of themachine comb from below upward this feeding device differs in certaindetails fromthat at the left. The position of the shafts 25 and 30 andthat of the supporting links 39 and 40 of the carrying frame 33' and oftheir points of support 41', 42 and 45, 46 is perfectly symmetrical withthat of the left'hand device, and the mode of operation of the entiredriving mechanism is also similar. On the other hand, the movable jaw 17of the clamp is arranged below, the two-armed lever 18 is formed as anangle lever, the connecting rod 22 is horizontal and the arms of thesecond angle lever 24 form an acute angle. The fixed upper jaw 15 isattached to a U-shaped crosspiece 16 which forms with a secondcrosspiece 16 a frame connected on its two sides with the frame 1 andwith the side wall 10. Screwed to the two side walls of the carryingframe and covering the end of the guide plate 36 is another guide member36 having a recess 37 for the feed roll 38 In contradistinction to thepusher plate 56 of the left-hand feed device which is trapezoidal inshape and is pivotally connected in the middle of the smaller face, theright-hand pusher plate 56 is rectangular. Its ends are connected bymeans of flat bars with the pivot pins 57 of the two angle levers 58, sothat the feed roll 38 and the carrying frame 33 are embraced. Two camsare here keyed on the shaft 30 and co-act with the antifriction rollers59 carried by the angle levers 58.

The left-hand stripping mechanism (Figs. 8 to 15 and 18) comprises theknown stripping rollers 61 and 62 and the endless apron or leather band63 which runs around the former roller and over a tensioning roller 64(Figs. 8 and 18). Stripping combs 65 and 66, whose arms are rotatableabout a shaft 67, move from above and from below in front of thestripping rollers. Further, the known striker 68 is provided whichprevents the beard torn off by the stripping device from contacting withthe rotating combing segment. This striker rocks about a shaft 69, aboutwhich swings in addition a lower comb 70 provided with a small groove ortrough 71. Atthe rear of the band 63 islocated a well-known flared guide94 and behind the same two stripping rollers 95 and 96.

The device for driving the two front stripping rollers 61 and 62substantially consists of a toothed sector 72 (Figs 10 and 11) havingtwo sets of teeth of different length with the shorter of which sets apinion 74 keyed on the shaft 73 of the lower roller 61 meshes. On thesame shaft is mounted, in addition, a ratchet wheel 97 into which a pawl99 pivotally mounted on a loose disk 98 takes. A second pinion 74 whichmeshes with the longer set of teeth of the sector is connected with theloose disk 98. The sector 72 rocks. about a shaft 75 journaled in theframe 1. In the arm of the sector is a slot 100 in which a pin 101 isadjustable. This pin is fast on a rod 102 which is pivoted in suchmanner at 104 to a gear wheel 103 that the latter constitutes a crankand reciprocates the sector 72 by means of the rod 102. On the samediameter of the wheel 103 as the pin 104 is mounted the pin 104 to whichthe connecting rod 102 for driving the right-hand stripping rollers isattached. The gear wheel 103 is keyed on the shaft 103 which is drivenby means of a gear wheel 135 keyed'on its other end (Figs. 16 and 17).This wheel 135 meshes with a gear wheel 134 fast on the shaft 30. Theshaft 30 is driven by means of the gear wheel 31 keyed on it by the gearwheel 8 which is driven, as described above, by the main driving shaft14. The toothed segment imparts to the roller 61 a so-called pilgrimsstep movement in the following manner:

lVhen the sector moves inward in the direction indicated by the arrow Iin Fig. 10 the pinion 7 4 and the disk 98 are rotated counterclockwise,as indicated by the arrow 1. This rotation is imparted by the pawl 99 tothe ratchet wheel 97 and by it to the shaft 73. This movement is thestripping movement for the roller 61. Toward the .end of this movementthe pinion 74 runs with the shorter set of teeth of the sector. lVhenthe movement reverses from that indicated by the arrow I to thatindicated by the arrow II both pinions 74 and 74 mesh with the sector 72and consequently rotate clockwise in the direction indicated by thearrow 2. As the pinion 74 is loose on the shaft 73, however, and as thepawl 99 slides over the teeth of the ratchet wheel 97 when moving in thedirection of the arrow 2, short rearward movement is imparted by theshorter set of teeth to the pinion 74 and to the stripping roller 61.

The lower stripping roller 61 is j ournaled in boxes104 of two arms 76rotatable about the shaft '75 (Figs. 8 and 9). Near the boxes 104 thearms 76 have eyes'105 into which spring-pressed links 106 are attachedwhich press the upper roller 62 against the lower roller 61. The rockarm 76 is provided with a branch arm 77 in which is adjustably journaledan antifriction roller 78 which bears against a cam 79. A springv 80constantly tends to press this roller 78 against the cam 79. As the arm76 is fulcrumed at 75, it is rocked forward when its arm 77 is lifted bythe cam 79. This cam is fast on a shaft 81 journaled at both ends in theframe 1. On the driving side of the frame a flying spur gear 82 is keyedon the shaft 81 (Fig. 18)

' this gear wheel 82 is driven by means of the intermediate gear wheel83 and 84 and an intermediate gear wheel 85 mounted on the same shaft asthe latter by the last gear wheel 9, and in this manner by the maindriving shaft 14. The rear roller 64 of the stripping apron or band 63is carried by a lever 86 which is influenced in such manner by a spring87 that the apron remains tensioned when the front stripping rollersmove forward and backward. The lower stripping roller 95 behind theflared guide 94 is driven by means of a ratchet wheel 107 (Fig. 8)mounted on its shaft 11.0, with which wheel a pawl 108 takes which ispivotally connected with the end of the shorter arm of an angle lever109 rotatable about the shaft 110; the longer downwardly directed arm ofthis lever is connected by means of a link 112, adjustable in a slot111, with one end of a rod 113 whose other end is pivotally connectedwith the abovementioned gear wheel 82. The link 115 can be adjusted in aslot 114 of the gear wheel 82. The upper stripping roller 96 is drivenby the lower roller 95. The upper stripping comb (Figs. 12 and 13) isdriven by means of a rod 88 whose one end is pivotally connected to theoutside end of one of the two levers 117 formed as twoarmed leversrotatable about the shaft 67 and carrying the comb 65. Above the shaft67 is placed a semi-cylindrical box 118 connecting the two levers 117.The rod 88 is pivotally connected at its other end to a lever 89. Thislever carries an antifriction roller 116 and is pressed by a spring, notshown, against a cam 92 keyed on the shaft 81, so that when the cam 92is rotated the upper comb 65 is moved up and down. The lower strippingcomb 66 (Figs. 12 and 13) is driven in the same manner. The comb 66 ispivotally connected to the shaft 67 by means of two arms 119 which arelocated outside the arms 117 of the upper comb 65. Pivotally connectedto one of the arms or levers 119 is a rod 120 which in turn is connectedwith a lever 121 rotatable about the shaft 75 and supported by means ofan antifriction roller 122 at its free end by a cam 123 keyed on theshaft 81. The lower comb provided with the box 71 is driven in a similarmanner. As shown in Figs. 14 and 15, two arms 124 lead from the comb 70to a semi-cylindrical box 125 which is located over the shaft 69 andembraces V the same. Pivotally connected to the onearmed levers or arms124 is a rod 125 which is attached to a pivot pin 126 on a one-armedlever 127 rotatableabout the shaft and carrying at its free end anantifriction roller 128 coacting with the cam 129 keyed on the shaft 81.The striker 68 which rocks downward is driven in the same manner. Thecurved plate 68 constituting the striker is carried by two levers 130,of which one is an angle lever; the two levers rock about the shaft 69and are located outside the arms 124 of the lower comb 70. Pivotallyconnected to the shorter arm of one lever 130 is a rod 90 which in turnis connected by a pin 131 with a triangular onearmed lever 91. Thislever likewise rocks about the shaft 75 and carries an anti-frictionroller 132 which likewise bears against a cam 93 keyed on the shaft 81.

The shaft 81 which drives the cams 92, 123, 129 and 93 is driven, asmentioned above, by the main driving shaft 14 by means of the gearwheels 9, 85, 84, 83 and 82 (Fig. 18). The levers 89, 121, 127 and 91are influenced by springs and continuously bear on their cams, so thatthe upper and lower stripping combs 65 and 66 and they lower comb 70 andthe striker 68 are driven positively. The right-hand stripping mechanismis exactly symmetrical with that described above.

The cleaning device of the combing segments (Figs. 16 and 17) comprisesthe known roller brush 133 which is rotated through the medium ofintermediate gears 135, 136, 137 and 138 by a gear wheel 134 fast on theshaft 30. The stripping or dofling roller 139 which is contacted by thecomb 140 rotates adjacent to the brush 133. Both the roller and brushare surrounded by a guard forming a box, from which a pipe 141 leads tothe hollow shaft 3.

Instead of the combs being arranged on the inside of the combingsegments they may be arranged on the outside thereof. Such anarrangement is illustrated in Fig. 2. In contradistinction to theapparatus de scribed above, in this embodiment the clamp is located onthe outside, while the stripping mechanism is arranged inside thesegments. The arrangement and mode of operation of the various membersis otherwise substantially the same as that described above.

Whereas in the embodiment first described above the wound rolls ofmaterial to be combed are located in between the segments, they are herelocated outside. The combed fleece is pulled by the endless apron orband 63* through the flared guide 94 and between the rollers 95 and 86and is conveyed into the interior of the stationary hollow shaft 3*,from which the curved sliver is drawn away laterally. The brush 133which re= wLAQ-Am MW 1 fibers to be placed one on another.

moves the noils from the combs is arranged with the dofling roller 139and the comb 1 10 likewise outside the segments.

The described machine operates as follows: Referring to Fig. 1, thesliver is conducted on the left-hand side of the machine from the rollercarried in the slots 35 of the carrying frame 33 over the guide plate36, over the rear feed roll 38 and under the front feed roll 38 which isintermittently rotated by means of the feed mechanism 53, 54, 55 whenthe carrying frame 33 moves forward, just as the feed roll 38 is rotatedin known manner by means of the feed mechanism 49-52. At each cycle ofoperations consisting of one rearward movement of the frame 33, when theclamp 15, 17 is closed, and one forward movement thereof, when the clampis open, the front feed roll feeds the corresponding portion of thesliver in front of the teeth of the combing segment then passing by it,which remove the noils from the length of fibrous material while theclamp is closed. The beard clamped between the jaws 15, 17 is thenpresented to the stripping mechanism after the combing segment hasperformed its work and the stripping mechanism has approached the clamp.The feed plate 56 which is then moving forward supports the beardhanging out of the clamp and, when the clamp has opened again, guides itto between the stripping rollers 61 and 62, so that these can seize thetip of the combed beard, whereupon the lower stripping comb 66 entersfrom below. In addition, the comb 7 0 enters behind the latter into thebeard from below, at the tip of which is a groove or slot 71 into whichthe upper comb 65 takes from above, so that the beard is now pulledthrough the two combs 66 and 65. The stripping rollers 61 and 62hereupon rock back and the combs .65 and 66 ascend and descend so thatthey are out of reach of the combing segments which now passes. Further,the striker 68 descends and remains in this position during the combingoperation in order to prevent the rear end of the beard contacting withthe combing segment. This end of the beard still rests between the tworollers 61 and 62 on the apron 63 in order that the tip of the nextbeard can be laid on the same, so that one connected sliver is obtained.In order that this may take place a pilgrims step movement is impartedto the lower stripping roller 61 by means of the two above describedsets of teeth on the combing segment 7 2, it being first moved a longdistance forward corresponding to the length of the fibers, and then ashort distance backward corresponding to the length of the endsnof efleece formed by the torn off beards is then removed in the form of asliver in known manner by the rollers 95 and 96 through the flared guide94.

The noils combed out by the combing seg ments are delivered to the brush133 which rotates at a higher velocity than, but in the same directionas the combs. They are then delivered by the brush to the dofiing roller139, from which they are removed by the comb 1 10 so that they fall intothe box surrounding the rollers, and are then sucked away through thepipe 141 and the stationary hollow shaft 3.
